Hi all,
I already know that there are many posts on this issue, but as I still can't fix my problem, I have decided to write a post.
Most of the images that I uploaded on Storyline are blurry or fuzzy. Those images have texts and are screenshots from software.
Any tips to improve the image quality? The original image quality is good and crystal clear.
Thanks in advance for your comments :)
Respectfully, the previous version did not cause the blurry images or text issue. The recommendation above may assist with some images, but I also continue to have blurry header lines and these are non-resized text boxes. I did attempt image resize to original on the attachment with no change
Hi everyone after updating to Storyline last version my images are blurry again :(
Hi Joane!
I see that you’ve reached out to our Support Engineers and are working with my teammate, Luiza. You're in great hands! We'll continue the conversation in your support case.
Hi Joane,
One of the more common causes of blurry images in a Storyline 360 course is mismatch between the resolution of the added image and the slide size of the project. The media library will give you a quick overview of the resolution of the images that you have in your course. You can also check out the article below to see our list of best practices to avoid the loss of media quality:
If the resolution of your images isn't too far off from the size of your slides, would you be willing to upload a copy of your project file here so we can take a look at what's happening?
Hi Joe,
I attached the original picture and a slide of my project that you can compare.
Hi Joane and Gina!
Thank you both for sharing those attachments! Are you seeing this with every image that you import into your projects or just specific images?
hi,
there is/was a (known) error with PNG without alpha channel, which was fixed with version storyline 3.63
April 20, 2022 (Build 3.63.27628.0)
Fixed: We improved how Storyline 360 handles images during import and in the published output, resulting in crisper images.
the error was the wrong import of PNG images (without alpha channel)
PNG -> import (as lossy jpg) -> publish as PNG (with alpha channel) in decreased quality
how to test -> test_image.story:
export '2022-06-14_144527.png' from the media library and test the file on
https://www.metadata2go.com/
result:
=> quality of all PNG images is (jpg) lossy !!!
there was no problem with PNG with alpha channel
there is no easy fix for 'old' projects - you have to re-import all affected PNG
Jürgen
ps: before the fix it was only possible to extend png with an (empty) alpha channel and then import it in storyline
Hi Jürgen,
Thank you for your comment. I think I fixed my problem by changing the slide size. Still blurry but better than before.
Hi Joane,
Sorry to hear that upgrading your Storyline 360 installation resulted in your images becoming blurry. Would you be willing to upload a copy of your project file here or in private by opening a case so we can review your image files? We'll delete it as soon as we're done troubleshooting.
Hi Joe and thank you for your reply. I opened a case and here is the case number 03318169.
